Application filed November .zenof the United States, residing at Bar rington, in the countyof Cook and State of Illinois, have invented certain new and use ful' Improvements in Locomotive erminal Houses, of which the following is 'a spec-i fication.

This invention relates to houses in; which locomotives are disassembled, repaired and reassembled, and particularly to a locomotive house in which means are provided for raising and lowering the locomotive bodil with relation to its'wheels or track;

The primary object of the invention isto provide a locomotive house with lifting and suppoiting means which, notwithstanding high lifting capacity and heavy construction, may be brought with ease into position alongside of the locomotive stall for operating upon a locomotive occupying the same, and which position relative to the locomotive will be determined with accuracy and maintained immovable and with great stability, particularly in directions of thrust that may be transmitted to the lifting apparatus by the load which it bears.

An object incident to the aforesaid primar object is to provide lifting apparatus, sub ivided into separately movable units adapted to be individually brought into the described relationship to the locomotive stall. Accordingly, one feature of the invention consists in providing alongside a locomotive stall, and paralleling the same, collateral trackage for the liftingapparatus, adapted to position and support such apparatus immovably in lifting relation to a locomotive occupying the stall, and providing a pair or pairs of elevating units mounted upon individual wheeled trucks, independently movable to and from operative position, but held in corresponding relationship to the locomotive when brought to operative position; each truck being constructed to support and present its lifting mechanism with stability and resistance to thrust which tends to displace it, and being in turn sustained in position by the track upon which it rests, transversely, by engagement of its wheels with the rai s, and longiby locking the Wheels, for instance, y self locking propelling mechanism.

Another object of the invention is to provide, in combination with lifting apparatus 9, 1923; sem mamof the kind'described, a'system' ofcollateral jtrackageiwhich will permit the lifting apf "PATENT OFFICE.

paiatu's to be brought F intooperative rela tion to any 1 onef'of' a n'um'ber of locomotive stalls at will. r'lnoth'erobj'ect of the invention is ro: 5

vide identical units of liftingapparatus' lation'to the locomotive stall will maintain the positions given to them, and 'whichwhen independently operated, for instance, by

fuhich-may be used in a pair,or pairs; which i when brought into selected position 'with' re--" another feature of the invention consists in providing wheeled trucks having self looking propelling mechanism by which they may be brought over the collateral trackage into selected positions in relation to the locomotivestall, and having mounted upon themscrew elevating mechanism with means for driving the same, which is substantially identical in all the units of the lifting mechanism, and whichmay be energizedin such a way as to cause all of the units to operate simultaneously and at equal speeds.

In the accompanying drawings, in which the preferred embodiment of the several features of the invention are shown by way of illustration Figure 1 is a diagrammatic view ofa portion of a locomotive house showing a plurality of stalls and collateral trackage related thereto.

Figure 2 is a section on an enlarged scale through a locomotive stall, and showing in elevation a pair of lifting units and the yoke beam through means of which they lift the body of a locomotive.

Figure 3 is a side elevation of a locomotive stall with one lifting unit of each of two pairs of lifting mechanism units in their operative relation to the body of a locomotive; and

Figures 4 'and 5 are, respectively, a side elevation and a top plan view of a portable lifting unit.

Referring more particularly to Figure 1, 1 represents a turn table, 2, 2", 2 and 2 a series of spur tracks radiating therefrom, and 3 3", 3, and 3 some of the locomotive stalls with which said spur tracks are connected. 4 represents a plurality of wheeled units which operate in pairs, and of which a pair or pairs constitute the lifting apparatus of the present invention, and 5 represents yoke beams resting at their ends upon the lifting units of a pair and constructed to underlie a locomotive body when in position upon the lifting apparatus. 6, 6, 6", 6, and 6 represent members of collateral trackage which are associated in pairs on opposite sides of and in parallel relation to the several locomotive stalls 3 etc., in such relation that they establish accurately and positively the relations of the liftin elements 4 when the latter are broug t in over the trackage to the sides of a locomotive occupying a stall; In order that the collateral trackage for any locomotive stall may be accessible to the lifting apparatus, the collateral tracks 6, 6, etc. are connected by branching tracks 7 7, 7 7 and 7 with turn tables 8 in a belt track 9.

Referring to Figures 2 and 3, 5 represents beams in the form of yokes adapted to rest at their ends upon elevating tables 11 of the lifting elements 4; said beams or yokes being constructed intermediately of their ends for underlaying the locomotive body or other structure to be lifted. As will be seen more clearly in Figure 2, when a body is lifted by means of yokes 10 resting upon tables 11, the engagement of wheels 12 of the lifting element 4 with the tracks 6 resist lateral movement of the body being lifted, and if means are provided for preventing revolution of the wheels, the positions of the lifting elements will be accurately maintained longitudinally of the tracks 6, and displacement of the body being lifted will be resisted in that direction.

In order to raise and lower the table 11, screws 13 are provided, and an electric motor 1 1 is arranged in driving relation to nuts 15 in which said screws are fitted. Screws 13 are preferably spaced apart in the direction of resistance to tipping of the tables 11 in order to increase the stability of the latter against the thrust of the load, and'if but a single pair of screws is used in each lifting unit, they may be spaced diagonally, or offset in the direction of both horizontal dimensions of the table and thus develop a component of stability in both said directions.

The elevating apparatus constituting each lifting unit is preferably constructed substantially as described in Letters Patent No. 1,450,702, issued April 3, 1923, to the present applicant, for improvements in wheel pit drop tables, and for a detailed disclosure of the essential portions thereof, reference may be had to Figures 1 and 5 of the accompanying drawings, wherein 16 represents a platform supported by revoluble nuts 17 upon screws 18 so that when the nuts 17 are rotated, for instance, by the motor l l acting throughbevel gear 19, pinions 20, 21, and bevel gears 22, the latter being mounted on the nuts 17 the platform will be elevated or lowered according to the direction ofrotation of the motor. And if the'screws 13, which are stepped upon the platform 16,

should be rotated by said motor 14 acting through bevel gear 19, pinions 20, spur 17 and screws'13 are rotated as described;

may be established or interrupted at will by mounting the pinions 21 and spurgears 23 with axial movement upon their shafts, and controlling such axial movements simultaneously through the medium of connecting rod 26 connected directly to the sleeve 27 which carries one of the pinions 21 and one of the spur gears 23, and indirectly through the reversing lever 28 with the sleeve 27 that carries the other pinion 21 and spur gear 23.

In order to propel the wheeled truck of an elevating unit 4-, a separate motor 29 is preferably employed and put under control of the controller 30. This motor has its driving pinion 31 in position to receive a driven pinion 32 axially movable into and out of mesh therewith by hand lever 33, acting through the medium of connecting rod 34: and sleeve 35 which carries said pinion 32. Any suitable source of electric current may be utilized for energizing the motors 14C and 29. A battery 36 is suggested for this purpose, and in order to control the delivery of current from the battery to the motor 14 and to determine the rate of revolution of the screw elevating mechanism a rheostat 37 may be employed.

As suggested at 38 in Figures 2 and 3, the beams 5 may be equipped with Wheels which adapt them to traverse a surface in moving to and from position of use, for instance, to be rolled to positions across the ends of a locomotive body and gradually warped into position beneath said ends; and in order that their deflected ends may rest upon tables 11, the beams are constructed with longitudinal sheer that brings their ends at a higher level than the intermediate portion. The wheels 38 are preferably connected-with the beams through means of caster mountings 39 so that the beams may be shifted sidewise as well as longitudinally; and these caster mountlngs are lo cated near the lower level of the beam. In order that the beams may be so worked into position, the track spaces will be leveled up loo in some suitable manner, as, for instance, by

surface paving or planking 40, or the like, as shown in Flgure 2.

I claim:

1. In a locomotive house, a plurality of locomotive stalls, pairs of collateral tracks for the respective stalls, paralleling said stalls, a track connecting all of said collateral tracks, and a pair of lifting units mounted for travel upon said collateral tracks and adapted to move thereover into lifting relation to a locomotive occupying any of said stalls.

2. In a locomotive house, a plurality of stalls for positioning locomotives, a pair of lifting units adapted to assume lifting relation to a locomotive when located on opposite sides thereof, collateral tracks paralleling the respective locomotive stalls adapted to position and sustain said lifting units in said relation to the locomotive, and connecting trackage and switches whereby said lifting units may be passed to any of said locomotive stalls at will.

3. A lifting beam adapted to enter beneath a structure to be elevated, said beam having wheeled supports that adapt it to traverse a surface to and from position of use and which support its ends above such surface to admit elevating units beneath them.

4. A lifting beam constructed with longitudinal sheer that presents its ends at a level above that of its intermediate portion, and having traversing wheels near its said intermediate portion.

5. In combination, a pair of elevating units adapted to be positioned on opposite sides of a structure to be lifted, and a yokebeam adapted to rest upon said units and extend from the one to the other thereof beneath the structure to be lifted; said beam being constructed with a longitudinal sheer that presents its ends at a substantial level above its intermediate portion.
